She smiled at them as they spoke to her. She nodded her head and said something to them. They both smiled. Then I saw the man between her legs slide h...s pants down to his knees. He was now standing between my wife’s legs in just his boxers. I could see a huge bulge in them. He pressed forward and spread her legs open even more. I knew he would now be able to easily slide his cock into her if that was his plan. Her wet lips glistened and were slightly parted. I thought I would cum in my pants. Rolling the wet lips around the nub, then pulling on them slightly, then dipping my fingers in her again, to massage the ooze of the wetness into her for more lubrication. She smashed her face against my neck and sucked in breath through the pillow – unable to do anything but concentrate now on the fact that she was approaching the edge of her shuddering orgasm. The heat on my hand was incredible, and I could feel the sweat coming off of the rest of her arm and her face. There was no way that. ”She smiled and moved her eyes to my pants, “Is that going to be permanent too?”I was on the verge of raping my sister so I had to deflect my thoughts, “Come on, move to the settee, you pose how you think you should.”Her eyes glinted with mischief, “You pose me, that’s what you do, right?”For the next 45 minutes I adjusted and moved my sister in modeling postures, taking pictures of her. I had her cup her tits in her hands, holding them so the nipples behind the see-through lace were the focal. Gramma came in wearing a white, floor length dressing gown. ‘Do you mind?’ she asked.‘No,’ I answered, backing up to let her in, ‘Not at all.’Gramma stepped into the room and locked the door behind her. As she turned to face me I noticed her eyes were drawn to my boxer shorts. ‘Cute shorts,’ she told me.‘Thanks,’ I said.‘I’ll bet what’s in them is even cuter,’ she said, reaching out and gripping my erection.
